Phylogenetic relationships of the genera of Ptiloneuridae (Psocodea, 'Psocoptera', Epipsocetae) and a test on the monophyly of Brasineura Silva-Neto & García Aldrete and Loneuroides García Aldrete.

The phylogenetic relationships of the genera of Ptiloneuridae were inferred on the basis of morphological characters of adult specimens.
